Fig. 3 illustrates when there is not NG pipe 54, is suitable for or complies with region 72 major part being located against the skin 70 of user and connecing Touch the skin of user.It is suitable for or complies with the outer surface in region 72 being formed, so make to be suitable for or comply with region 72 or canal path substantially follow the profile identical with the remainder of mask buffer pad 58.This configuration contribute to being suitable for or The face 70 complying with region 72 and patient seals, and this will preferably form less than one in the case of lacking a NG pipe 54 Insignificant leakage paths.Substantially follow the geometry of remainder of cushion pad 58 for being suitable for or complying with region 72 For be useful because this configuration will make face shield 52 for being used for the use than originally the most possible user wider scope It is more general on person and more suitably.Such as, shown face shield 52 can be any user needing NIV to treat or patient Upper use, is used together with many pipes in spite of needs.Preferably, be suitable for or comply with region 72 towards patient or contact These adjacent parts of surface and cushion pad 58 or these peripheral part define a company towards patient or contact surface Continuous or continual surface.That is, it is preferable that be suitable for or comply with being suitable for or comply with in region 72 or neighbouring this Region towards patient or contact surface not existing crack or other interrupt.

In some configurations, the outer surface of cushion pad 58 there may be a slight step.This slight step can Be intentionally or be suitable for or comply with the result of the material in region 72, configuration or manufacture process for being formed.This step Can be sufficiently small such it will produce minimum leakage.Be suitable for or comply with region 72 can be sufficiently flexible in case by Expand under the air pressure that treatment applies, so make the part swollen otherwise may be caused by the step filled in this surface Any gap.

As described above, it is suitable for or complies with region 72 and can have being intended to for being used together with face shield 56 The type of 54 or many pipes of pipe or size provide any suitable arrangement of compliance.In some configurations, it is suitable for or complies with Region 72 is the most more suitable for compared with peripheral part of cushion pad 58 or adjacent part or complies with.At some configurations In, the adaptability of increase or compliance are at least partly to be suitable for or complying with in region 72 periphery relative to cushion pad 58 Divide or the result of adjacent part a kind of different materials of use.Such as, a kind of more elastic and more flexible material can be used by local Material realizes adaptability or the compliance increased.This different material can have the multiple peripheral regions or many with cushion pad 58 The material of individual adjacent area compares higher elasticity or different elastic modelling quantity.But the most not limiting, material can wrap Include the hardest a kind of different grades of silicones or a kind of more flexible TPE.In some configurations, different materials also may be used (such as, less with the thickness that there is the material of the multiple peripheral regions with cushion pad 58 or multiple adjacent area different Thickness).Different materials can be connected to multiple peripheral regions of cushion pad 58 or multiple phase by any suitable process On the material in neighbouring region, but the most do not limit, this any suitable process can include adhesive agent combine or chemical bond, An or co-molded or cladding molding process, or any other suitable method.Be suitable for different materials is used for or Complying with in the arrangement in region 72, this different material can extend beyond and be suitable for or comply with region 72.Such as, this arrangement can Think the surface depressions providing bigger that is bonded to each other by bi-material.

In some configurations, it is suitable for or complies with region that region 72 is a thinning material or include a thinning material The region of material.In the arrangement shown by Fig. 4-Fig. 8, it is suitable for or complies with region 72 including the region of a thinning material, The region of this thinning material is the material that the material of the multiple peripheral regions with cushion pad 58 or multiple adjacent area is identical.Cause This, the region of this thinning material can by with multiple peripheral regions of cushion pad 58 or multiple adjacent area monolithic molding.Hereinafter, It is suitable for or complies with region 72 being referred to as a thin region or weakened region.But, in view of to being suitable for or complying with region These alternative structure of 72, this type of reference to a thin region can also generally include other kinds of being suitable for or suitable equally Answer region.It is suitable for or complies with region 72 limiting the face 70 adapting to NG pipe 54 or other pipes at cushion pad 58 with user Between one or more canal path of passing, and therefore can also be referred to as a canal path at this.In some configurations, one Individual or multiple canal path 72 are formed thinner than these adjacent parts of cushion pad 58.In some configurations, one or more Canal path 72 is formed thinner than any other part of cushion pad 58.

Fig. 4-Fig. 8 illustrates the cushion pad module 64 being separately from other sections with face shield 52.As described, cushion pad module 64 include shell 66 and sealing member or cushion pad 58.In shown arrangement, being suitable for or comply with region 72 of sealing member 58 It is a thin region or includes a thin region.Preferably, thin region 72 is limited by sealed wall, and this thin region 72 is relative to slow Multiple peripheral part of die head 58, multiple adjacent part or other parts multiple more can meet pipe 54.Cushion pad 58 generally has There are patient facial region's contact portion or side 90 and face-contacting portion 90 part forward or side 92.Face Contact portion 90 be typically towards after, and contact the face 70 of user.Face-contacting portion 90 can be placed with Deform when contacting with the face 70 of user, and whole rearward portion can not contact institute under all situations or treatment There is the face of user.In shown configuration, a upper part of cushion pad 58 can be relative to the one of cushion pad 58 Lower part deflects forward, in order to better adapt to the change of the nose geometry of potential user.PCT Publication applicant Disclosing the example of this arrangement in number WO2014/062070, the full content of the disclosure is combined in this also accordingly by quoting And become a part for present disclosure.But the most not limiting, cushion pad 58 can be by one or more generally flexible materials Material is made, such as silicones or TPE.

In figures 4 and 5, the position in thin region 72 is shown by a profile on the outer surface of cushion pad 58.So And, it is preferable that as Figure 6-Figure 8, thin region 72 is limited by a depression 94, and this depression is limited by the inner surface of cushion pad 58 Fixed.The geometry in thin region 72 can be constructed or be adapted to meet and be intended to for being somebody's turn to do or these with what face shield 52 was used together The size of pipe or shape.In some configurations, thin region 72 can be at least partially or completely positioned at the face of cushion pad 58 In portion's contact portion 90.With reference to Fig. 5, thin region 72 generally from an inward flange 96 of face-contacting portion 90 towards face One side of one outward flange 98 of contact portion 90 upwardly extends.In some configurations, thin region 72 can be with inward flange 96 Spaced apart with one or two in outward flange 98.In some configurations, as shown in Figure 4, thin region 72 can extend beyond face The outward flange 98 of portion's contact portion 90, and extend in the front portion 92 of cushion pad 58.

In some configurations, thin region 72 becomes relative to a horizontal axis 100 of cushion pad 58 or cushion pad module 64 Angle.One vertical axis 102 can be halved cushion pad 58 or cushion pad module 64, and horizontal axis in vertical direction 100 are perpendicular to vertical axis 102 and extend on the horizontal direction of cushion pad 58 or cushion pad module 64.The one of thin region 72 Individual axis 104 and horizontal axis 100 can be limited between about 5 degree and about 45 (if or needing bigger) betwixt One angle.In a kind of configuration, this angle between axis 104 and horizontal axis 100 is about 20 degree.In shown peace In row, a inner 106 closer to centrage or vertical axis 102 in thin region 72 than thin region 72 further from this center One outer end 108 of line or vertical axis 102 is higher.This typical path arranging to adapt to NG pipe 54 as shown in Figure 1.So And, as desired, thin region 72 can be arranged in other orientations, in order to is suitable for other application.Such as, mouth stomach (OG) pipe In about 0 degree or cushion pad 58 can be extended through substantially along horizontal axis 100.Therefore, in view of specific tube, pipe orientation Or other correlative factors, can select the specific orientation in thin region 72 as desired.

Thin region 72 can have to be constructed or be adapted to meet is intended to for being somebody's turn to do or these with what face shield 52 was used together The size of pipe or shape.In shown arrangement, thin region 72 defines that extension is many between inner 106 and outer end 108 The lateral edges 110 and 112 of individual substantial linear.These lateral edges 110 and 112 can be substantially parallel to each other.Axis 104 is permissible It is defined as parallel lines equidistant with these lateral edges 110,112.In some configurations, in the inner 106 and outer end 108 One or two can have a cavetto or the most semicircular profile, as shown in Figures 4 and 5.This geometry Shape will cause the thicker side wall construction of cushion pad 58 to dock with the circumference of NG pipe 54, and thin region 72 is in this thicker side Deform between wall and pipe 54.Thin region 72 can be sufficiently thin to deform above a NG pipe 54 and stretching, for This NG manages, and face shield 52 is intended to or is approved in the case of not lifting cushion pad 58 away from the face 70 of patient significantly Use.In some configurations, do not lift or there is no and lift and will occur.Meet region 72 these ends 106, The geometry of the cavetto of 108 can minimize the relatively thick Adjacent walls portions by cushion pad 58 make NG pipe 54 deform or The probability shunk.

Fig. 6-Fig. 8 illustrates the thin cross sectional view meeting region 72 of cushion pad 58.In shown configuration, cushion pad 58 Inner surface can reduce from relatively thick wall section or be stepped down to relatively thin and more adaptable Part 72, in order to limiting inner recess 94, this outer surface can keep being basically unchanged simultaneously.In other words, this outer surface is at Bao Qu It is continuous and unbroken between these adjacent parts or these peripheral part of territory 72 and cushion pad 58.But, at some structures In type, this outer surface can include in addition to inner recess 94 or substitute a depression of this inner recess, and can depend on The swelling of result as air pressure inside is relied to form of the face 70 with user in the case of lacking a pipe 54 Seal.

Depression 94 can limit a length 114 on the direction along axis 104, and is being perpendicular to axis 104 A height 116 is limited on direction.Length 114 can be selected under typical or intended operating condition, along possible The length of the face-contacting portion 90 contacted with the face 70 of user extends.In some configurations, length 114 is about Between 15mm and about 20mm.Length 114 can change with the size of cushion pad 58, or can be in different size of buffering Keep constant between pad 58.Such as, length 114 can change to for one big from the about 15.5mm of a minibuffer pad 58 About 19mm or 19.3mm of cushion pad 58.Highly 116 can be selected to adapt to face shield 52 is designed or is intended to therewith Use should or the diameter of these pipes or sectional dimension.In some configurations, highly 116 are substantially equal to slightly larger than face shield 52 quilt Design or be intended to the diameter of the largest tube size being used therewith.In some configurations, highly 116 is with big at about 5mm Between about 15mm, or between about 10mm and 12mm.Highly 116 can change with the size of cushion pad 58, the most right Being about 9mm in an extra minibuffer pad, for one, little and medium cushion pad is about 10mm, and for one Individual big cushion pad is about 11mm.Alternately, highly 116 can keep constant between multiple cushion pad size.

Thin region 72 limits a wall thickness 118, and this wall thickness than cushion pad 58 is neighbouring or many around thin region 72 One wall thickness 120 of individual part is less.Preferably, the wall thickness 118 in thin region 72 is less than wall thickness 120.At some structures In type, wall thickness 118 is about the 5% to about 80% or about 10% to about 30% of wall thickness 120.At some structures In type, wall thickness 118 represent relative to wall thickness 120 on thickness between about 70% to about 95% or big Minimizing between about 80% to about 90%.Such as, in some configurations, wall thickness 120 can be about 1.49mm or 1.5mm, and wall thickness 118 can be between about 0.1mm and about 0.5mm, or at about 0.15mm and about 0.3mm Between.In some configurations, wall thickness 118 is about 0.3mm.Wall thickness 118 in depression 94 is shown as substantial constant (these transition portions not included between depression 94 and these peripheral part or these adjacent parts of cushion pad 58).So And, in other arrange, wall thickness 118 can change in depression 94.

Cushion pad 58 can from patient contacting portions 90 at the height in thin region 72 at one the most backward and A degree of depth 121 (Fig. 8) is limited in one forward-backward directions of the position of the outer end 108 in thin region 72.There is one enough The degree of depth 121 cushion pad 58 can be helped to keep in the case of a NG pipe 54 is in appropriate position and the face 70 of user Contact.It is preferable, however, that the degree of depth 121 is unsuitable excessive, or thin region 72 does not extends towards the front portion 92 of cushion pad 58 Too far or extend in this front portion, in order to avoid unnecessary the weakening of cushion pad 58.The degree of depth 121 can be with face shield 52 The size being designed, be intended to or ratifying the pipe 54 for being used therewith is correlated with.In some configurations, the degree of depth 121 is greatly Between about 10mm and about 20mm, or at about 15mm and more than between 18mm.The degree of depth 121 can be with the size of cushion pad 58 And change, it is such as about 14mm or 14.3mm for an extra minibuffer pad, is big for a medium cushion pad About 15.7mm or about 16mm, and be about 17.8mm or 18mm for a big cushion pad.Alternately, the degree of depth 121 Can keep constant between multiple cushion pad size.

In some configurations, the thickness between the depression 94 of cushion pad 58 and these adjacent parts or these peripheral part Transition can be sudden change relatively.The transition of this sudden change can form a folding point, and this folding point limits may be by a pipe The deformation in the relatively thin region 72 of caused cushion pad 58.Relatively thin region 72 can deform, stretches and/or be polymerized to one Group is until running into a relatively thick wall part, and this relatively thick wall part can limit any further deformation.? In other configurations, the transition of thickness can less suddenly change, such as these dotted line institutes of these edges by the depression 94 in Fig. 7 Show.Due to other reasons (such as manufacturability reason), transition that is a kind of smooth or that less suddenly change can be preferred.Excellent Choosing, this transition is limited to a relatively small distance of distance depression 94, or the relatively small region around depression 94.Example As, this transition can be substantial linear and/or can be the buffering that be enough to allow a molding by having thin region 72 Pad 58 is from an actual angle removed of mould.In some configurations, this transitional region is preferably distal from thin region 72 and prolongs Stretch a distance of the width less than thin region 72 or length, and preferably extend not more than width or the length in thin region 72 A part (such as, less than width or 1/2nd of length, 1/3rd or 1/4th in thin region 72) for degree.

Fig. 9 illustrates an example of the profile being in one of flat form depression or thin region 72.It practice, thin region 72 be probably bending in shape or three-dimensional because many patient contact surfaces of mask buffer pad horizontal direction and/ Or be bending in vertical direction.In fig .9, each end 106,108 in thin region 72 is around a correspondence in shape The semicircle at center 122.Therefore, the distance 124 between these centers 122 is plus the radius etc. of each end 106,108 Total length 114 in thin region 72.In shown thin region 72, these lateral edges 110,112 are parallel to each other, and end 106, each in 108 has an equal radius.But, in other arrange, thin region 72 can have other and close Suitable shape.

In some configurations, all configurations as shown in Figure 10, these meet thin region or canal path 72 can be set In multiple positions.Figure 10 illustrates the rearview of the cushion pad 58 with two canal path 72, and these two canal path are along buffering One circumference of pad 58 is spaced apart from each other, and is symmetrically located on every side of face shield 52.Every side of face shield 52 has Have multiple path 72 to allow a NG pipe 54 to be fixed on the either side of face 70 of patient.For NG pipe 54, one Alternately so that the stimulation reduced in nasal passage and tissue injury are accepted practices between the nostril of name patient.Face shield 52 has The canal path 72 having multiple symmetry makes a clinician can change the side that NG pipe 54 is fixed to, and is continuing with Same face shield 52.This configuration reduces equipment loss, and can reduce the work of clinician.Additionally, two sides On have when multiple canal path 72 makes a cushion pad 58 can use a NG pipe 54 and a NJ pipe at the same time and seal.

Figure 10 it is also shown that the size of two kinds of different canal path 72.Because NG pipe 54 has multiple size, for For these canal path 72, it is possible to meet any size or at least conventional size is useful.A face shield 52 has Have more than what a kind of path sizes can be desirable to, in order to cover wider in the case of the most acceptable leak rate performance The pipe diameter of scope.If a pipe is too small for canal path 72, the relatively thick wall section of cushion pad 58 may not Limiting the deformation in thin region 72 fully and be likely to be formed multiple gap, these gaps can cause leakage.Canal path 72 Size can be defined to be suitable for the pipe diameter of a certain scope.As discussed above, for the round shape/circle of canal path 72 For profile, generally relevant to this pipe diameter or coupling is desired.By by canal path 72 and pipe 54 tight fit Or the most relevant, this relatively thick wall section can force thin region 72 to meet around pipe 54.

Not there is too much canal path 72 or excessive canal path 72 is preferably as they can reduce cushion pad The structural intergrity of 58.The relatively thick wall section of cushion pad 58 can be designed to provide structure and support to face shield 52. Cushion pad 58 can be equipped with for being reduced or eliminated cushion pad 58 collapse when being bundled on a patient 50 by face shield 52 The structure of probability.If cushion pad 58 collapse, leakage it may happen that, and rigidity plastics mask frame 68 can be located against suffer from The face 70 of person promotes thus causes discomfort.Therefore, quantity and the size of multiple canal path 72 can be constrained to so that buffering The structure of pad 58 is the most impaired.Such as, cushion pad 58 can include any single canal path 72 shown in Figure 10 or Any combination of these canal path.In some configurations, cushion pad 58 can include single canal path 72 on side, or Single canal path 72 is included on every side.Have in the configuration of at least one canal path 72 on each side, these canal path 72 Can be formed objects or different size.Such as, cushion pad 58 can include a relatively small canal path on side 72, and include a relatively large canal path 72 on another side.In some configurations, cushion pad 58 wraps on each side Include a little and big canal path 72.

Typically, NG pipe 54 and is outwards stretched across buccal across their lip from the downside of the nose of a patient Long.Pipe 54 generally utilizes adhesive tape to be fixed on nose.One or more canal path 72 are preferably located on cushion pad 58, so They are substantially directed at or slightly lower with the lower surface of the nose of a patient, so make these pipes 54 can be right In being fixed on patient 50 by the wieldy substantially conventional position of clinician.For pipe 54, it is located at Below the top of the soft of the buccal of one patient, cheekbone can be useful Anywhere, in order to minimize pressure ulcer Generation.Make these canal path 72 be positioned at by this way on cushion pad 58 will to allow the clinician to be continuing with for Assembling and the conventional art of fixing NG pipe 54.In some configurations, these canal path 72 are positioned in the latter half of cushion pad 58 Or in lower three/part of cushion pad 58.These canal path 72 may be located at one of a full-face cushion pad 58 At wide point, positioned adjacent or the most above it.In some configurations, these canal path 72 are at one of cushion pad 58 One minimum point of inward flange spaced above.

Figure 11 A and Figure 11 B illustrates a cushion pad module of a face shield 52 with multiple vision alignment designator 130 The embodiment of 64.These designators 130 are it is intended that clinician provides a face for the over top at a NG pipe 54 The visual cues that cover 52 is aligned on the face 70 of a patient.In order to shown face shield 52 works effectively, for For NG pipe 54, it is precisely directed to be desired relative to these canal path 72 on mask buffer pad 58 by it.Misalignment The leak rate increased may be caused.These alignment designators 130 can be in an arrow and the label pointing to NG canal path 72 Form.Designator 130 can be close to canal path 72 and be positioned at as illustrated in figure 11A on cushion pad 58, or such as institute in Figure 11 B It is positioned at showing on mask body (such as, shell 66 or framework 68).Embossing, printing, laser-induced thermal etching, molding or other labelling techniques Can be used on face shield 52 forming designator 130.
